I tried to get a pair of them to use with my Sarkens, so I could use them on a few different pairs of boots (with and without the toe welt). Petzl refused to sell them to me and said they will not work on that model. This doesn't make much sense, why would they work on the Lynz but not the Sarken?

I have a friend with Lynx 'pons and he doesn't use the non-welt piece, so he gave them to me. They fit great on my Sarkens and work awesome.

So the short story here is that Petzl customer service sort of blows. Good to see someone else making the same type of thing, so buyers have an option.

Petzl also has these for the Lynx crampons. I tried to get a pair of them to use with my Sarkens, so I could use them on a few different pairs of boots (with and without the toe welt).
